A new log-periodic antenna (LPA) geometry is presented in this study. The LPA is considered to be composed of 14 wire dipoles with lengths and distances that follow an exponential rule. This geometry ...

Abstract: A new geometry of log-periodic dipole array (LPDA) is presented in this work. Unlike the traditional LPDA geometry, where all dipoles are considered to be inside the same angular sector, the ...

The asymptotic behaviour of the first-passage-time p.d.f. through a constant boundary for an Ornstein-Uhlenbeck process is investigated for large boundaries. It is shown that an exponential p.d.f.
